How to make a two-point perspective render?
It seems this is not possible to do the same way as Yafaray, however you can do it with camera positioning and tweaking the Shift values.

From the wiki:


   Two Point Rendering
  
  Normal architectural
  rendering is called two point rendering; when vertical lines are
  parallel, and horizontals, if followed out to the side, converge on
  one point, and receding or depth lines converge to a second point.
  
  Architects often like this Two-Point rendering, so that the sides of
  their buildings are completely vertical and don't appear to be falling
  inward. This is also quite nice for compositions and schematics, given
  that the lines of the paper you print on and the screen you view with
  are also straight. 
  
  Previously to get a 2-point perspective, you had to
  aim the camera level to the horizon, however this resulted in the top
  half of the building being cut off and the horizon being in the exact
  middle, which looks very boring. Architectural photographers use
  'shift lenses' to solve this problem. Shift lenses shift the image to
  another place on the film. Two Point Horizontal Render This technique
  works well for high buildings as well as for normal sized objects.
  
  Most of the time, the two vanishing points are horizontal and depth
  lines, with the vertical lines parallel. However, some titles are done
  with the horizontal lines parallel, and the vertical and depth lines
  having the vanishing point. This dramatizes and exaggerates the
  massiveness and height of the title.
  
  To get this effect, position the camera at ground level, centered,
  angle the camera upward, and shift the render passpartout down. In the
  example, the camera is rotated 30 degrees upward, at ground level with
  the title. A bright key light with a short falloff provides dramatic
  lighting that is bright in the middle and falls off toward the sides,
  further enhancing the depth. 
  
  To achieve 2-point rendering:
  
  
  Use a short wide angle lens camera, say with a Lens Size of 10 mm placed close to the building, or a long lens farther away from the
  building. These differences affect the depth of the building render,
  with longer lenses making the building appear thinner and less
  dramatic or distorted. The example uses a 40mm lens. 
  Position the camera off to one side of the object, vertically halfway up the building to minimize distortion of the vertical
  building edges. You may alter this vertical (Z value) position to be
  slightly higher than ground level or higher than the top (if you want
  to see the top of the object or building). To show the front bottom
  corner of the building jutting out, raise up the camera. 
  Angle the camera to be looking away from the building and directly level at the horizon - not pointed up or down (note the 20 degree Z
  angle in the example). This should make the vertical lines parallel.
  The more the camera looks at the object, the closer the vanishing
  point for the horizontal lines, and perceived depth will increase as
  that vanishing point gets closer as well. 
  You may have to angle the camera slightly down (just 1 degree or so) so that vertical lines appear vertically up and down, both near
  and far. If the lines are curved, use a longer lens. With your 3D View
  set to Camera view, use the passpartout or pixels on your monitor to
  determine vertical. 
  Move the camera toward/away from the object until it appears near a corner of the render and is the right size. 
  Adjust the Shift: X and Y settings until your object is positioned properly.
